The North Face One Bag Deep Dive (Field Tested)

I would put this somewhere between a dedicated backpacking bag and a full truck-camping sleep setup.

The One Bag is not for an ultralight backpacker.

It is also not for someone with three dialed sleep systems already hanging in a gear room.

If you already own purpose-built bags for every scenario, this probably solves a problem you no longer have.

But if you are still building your gear system, or if you just want one sleeping bag that can realistically cover a huge range of use cases, this starts making a lot of sense.

Mid-summer.

Long backpacking trips.

Any situation where space and weight become a priority.

I reach for the One Bag when temperatures drop below roughly 60 degrees and I am not hiking deep into camp.

Truck camping.

Hunting camps.

Unpredictable forecasts.

Trips where weather could go sideways.

It is one less thing to think about.

The zipper system is not hard.

But I would absolutely recommend learning it before you actually need it.

Throw it on your bed at home.

Zip and unzip the layers.

Figure out what connects where.

Once you understand the setup, it becomes easy.

Going in cold at camp after dark while trying to figure out multiple zippers for the first time sounds a lot less fun.

The other tradeoff is bulk.

There is really no getting around it.

A layered system simply takes up more room.

Packed size is noticeably larger than most dedicated backpacking sleeping bags, especially once everything is compressed into the stuff sack.

I have never cared because I have mainly used this for truck camping, hunting camps, and trips where I am setting up near camp.

If I had to hike several miles with all my gear, I would think differently.

Idaho was probably the perfect test.

During a five-day hunt, overnight temps bounced between roughly 25 degrees and around 50.

That kind of swing is exactly why this system exists.

Instead of crossing your fingers and hoping your sleeping bag choice works, you can actually adjust things.

I have also used it in my truck tent, camping in Maine, and sleeping in the bed of my truck on an Uncle Elk air mattress.

Different setups. Different temperatures.

Same bag.

This was also my first mummy-style bag.

I expected to hate it.

I am a bigger guy and figured I would feel trapped immediately.

That never really happened.

There was still enough room to move around without feeling like I got vacuum sealed into nylon.

If you hate restrictive sleeping bags, I think this is worth mentioning.
